Answer 1

Make string variable in your AppDelegate Like

var Model_id = String()

and where you are getting value of username and userid sends its value to AppDelegate. make AppDelgate object like below and same in destinationViewController

let appDelegate = UIApplication.shared.delegate as! AppDelegate

to pass value to app delegate variable

self.appDelegate. Model_id = "your Value"

and get your values wherever you want to fetch like below

let appDelegate = UIApplication.shared.delegate as! AppDelegate
let  string = appDelegate. Model_id as! String
